Ed was shopping with the boys from Rixton who are supporting him on his ‘x’ World Tour in Canada, when he heard a fan singing his song ‘Thinking Out Loud’ in the mall.

13-year-old Sydney Bourbeau was performing Ed’s hit in a fundraiser for her music school which was being held at a shopping centre when Ed himself walked past and decided to join her on stage.

When Ed hopped up on stage with her, Sydney first thought it was someone coming to fix her microphone, and didn’t know whether to keep singing or to talk to him.

She told the Edmondton Journal, “I was like, should I stop? I didn’t want to stop, but I wanted to talk to him. This is, like, the best thing that’s ever happened to me. I was so happy that he did that, it was incredible.”

But like a true pro, Sydney embraced her duet with one of the biggest music stars of the moment without missing a beat – luckiest girl ever?
